I love your four armed girlie, I got to know how you made it
This body is based on Option parts set 6 and 7. The second pair of arm socket is cut and glued with sprue goo. Then I cut off the side of body part, and shaved off some plastic to avoid collision against the middle body (belly part).
This method requires irreversible process only on the upper body part (neck-arms-chest part). The second pair of arm joint limits movement of the upper body, but this is still very clean and straightforward way to do.
I hope this helps!
